    Hi
    I have had some problems that the starboard engine shuts down, no alarm occurs. I just turns the key back on off then back at on and I can start the engine again. The last trip I had 4 shutdowns in 30 min. Any good ideas

    My first guess (strictly that) would be a fuel blockage, but it could be so many things.

    A fuel issue would also result In other symptoms like low pressure, rough running, power loss. It sounds like an electrical or control problem. Loose wire or cable. If your engines can be started from the ER, try that and see if it shuts down.

    Way too many possibilities and way too little info. Yep, could be electrical, brain or..... DK what other symptoms he had (like were his RPMs fluctuating), Given that it could be fuel flow and that's easy to check, but I suspect he has a visit from a mechanic in his near future if it's not fuel flow.

    The engine is running perfectly but shutting down at once. It is like you just turn the key at of. Rpm indicater is standing on the the rpm that the engine is running. Thereafter I can start it again. I also think it is an electrician problem. But it could have been interesting if someone have had same problems

    Yep, sounds like time to plug in the diagnostics.

    If there are no alarms, nothing for the computer to diagnose (no codes). Being so intermittent, it would be impossible for the laptop to catch the shutdown code at the dock or within a reasonable amount of time. Fuel flow would show as an alarm. This is electrical, like the computer is seeing the key switch being turned off.

    Try replacing the key switch and checking all harness plugs, then with the motor running start physically moving wires around and jiggling harnesses and see if you can duplicate the problem. Then have a marine electrician check all of the wiring on power supplies on the key switch circuit, harness connections, power supplies to the computers, batteries, battery connections. etc. etc. Sounds to me like a bad wire, bad connection, or key switch.

    And do not overlook any ground wires to the ECUs, displays etc. years ago I had a fairly new car which would suddenly and randomly go into limp mode. Dealer could t figure out because there were no codes until an old fashioned mechanic checked the ground wire to the ECU... sure enough it was loose.

    and I said earlier, next time start the engine from
    The ER and see if it still happens.

    Hi did you ever find a solution. I have the same problem. I think its temperature related in the engine room. Once the temp goes above 42c the gauges reboot and then the engine stops and restarts. Had it happen at 2000rpm and 1000rpm. Check all wiring and cant find anything. No error codes apart from one time which was SE05 nd05 10+A001-sam can bus-1 error/bus defect

    Hi
    I have the same problem on my MTU engines.
    It's the blue line electronics and also a friend of mine has tge same problem.
    The ignition keys have been bypassed but problem remains.
    Now he cleaned all connectors.
    In my boat it occurred 2 times when I hit a wave so definitely a connection that is bad or a cable that has some corrosion.
    If someone has some advice please let me know
